IMPROVEMENT IN FLoUR-BoLTlNG MACHINES.'

Specification forming part of Letters Patent No. 210,186, dated November 26, 1878; application filed Y September 13, 1878.

To all whom it may concern:

Be it known that I, MILES P. CLEMVIR, of Pin Hook, in the county of Gaston and State of North Carolina, have invented certain newl and useful Improvements in Bolting Apparatus for Flour; and I do-hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it', reference being had to the accompanyin g drawings, which form part of this specification. Y 1

My invention relates to an improved bolting apparatus for bolting ilour.

Heretofore boltin g-reels have ordinarily been employed for boltingour, which are expensive, both in first cost and to keep in repair. The clothing for reels is very expensive, as about twenty yards are used in covering a reel, and owing to the fact that such clothing is often torn and destroyed by bugs, it is a matter of considerable expenseto keep the ordinary boltin g-reel in proper condition for use. 1

The object of my invention is to provide' a bolting apparatus of suchl construction that but a small quantity of bolting-cloth will be required to clothe the hinting-receptacle; and

v to that end my invention consists in a bolting apparatus of the peculiar construction as will hereinafter appear from the following descrip- ,tion and claim.

In the accompanying drawings, Figure lis a vertical longitudinal section of my improved bolting apparatus. Fig. 2 is a similar view, showing the bolting-trou gh at its highest point of travel. Fig. 3 is a plan view of the frame; and Fig. 4, an end view of the bolting-trough, and mechanism for operating the same.

A represents the frame of a bolting apparatus, provided :with spouts or pockets B C D, which latter may be arranged as desired, and of any suitable number. To the ends of frame A are attached cleats a, for guiding the uprights E, to the lower ends of which the opposite ends of the bolting-trough F are secured. '.Ihe frame of the bolting-trough consists of the ends b and side pieces, c.

G represents the bolting-cloth, which is arranged on the trough on the same principle as on a reel, sections d and e being of different I size of mesh for the different grades of bolting. The bolting-cloth is attached to the bottom of the trough throughout its entire length, andthe top may be covered by ordinary thick heavy cloth, or by strips of boards, as desired. To the top H of the frame is secured a funnel, having the upper end of a flexible conveyer attached to its lower end, the opposite end of said conveyer being attached to the top of the bolting-trough. This construction and arrangement of conveyer allows of the continuous feeding of the flour to the boltingtrough while the latter is in motion.

The trough is arranged at a slight angle of inclination, so that the coarser particles may be carried gradually from the head to the tail L are pitmen, their upper ends being pivoted to the upper ends of the uprights E, while their lower ends are attached to wrist-pins secured to the outer faces of the crank-wheels.

Thev shaft I is provided with a belt-pulley, andmay be driven by power from any convenient source. By imparting a rapid rotary motion to the shaft I the bolting-trough is rapidly reciprocated in a vertical direction. Flour is poured into the funnel attached to the top of the frame,rand is 'conveyed to the rapidly-reciprocatin g bolting-trough bymeans of the flexible conveyer.

As the contained iiour in the bolting-trough is constantly subjected to the vertically-shaking action of the bolting-trough, caused by the passage of the upper and lower dead-centers of the wrist-pins, the flour will be most thoroughly and rapidly bolted.- That portion of the iiour that is too coarse to fall through the meshes of the cloth-located nearest to the head of the bolting-trough will be gradually carried down to the cloth having coarser meshes, and such particles as will not fall through the meshes of the cloth nearest the tail end of the trough will be discharged from the lower and open end of the trough.

My improved bolting apparatus 'is simple in To the ends of shaft I the its construction, and can be supplied With bolting-cloth at a slight expense.

I am aware that the shoes of middlings-separators have been made to be reeiprocated in a vertical plane, and hence I make no claim to such construction; but,

Having fu1ly described my invention, what I claim as new, and desire to secure by Letters Patent, is

The eon1bination,With a bolting-trough suspendedwithin the frame or casing of the apparatus by means of rigidly-attached end supports, which move in guides and project above the top of the casing, of a driving-shaft provided with crank-Wheels ou opposite ends j thereof, and pitmeu pivoted to the bolt-trough supports and to Wrist-pins ou the crank-Wheels, substantially as set forth.

In testimony that I claim the foregoing I Witnesses: C. H. ABERNETHY F. W. THOMPSON.
